Shaggy, When a buck has a doe on his mind they can be very difficult to stop. I have stopped some and haven't many others. I've seen times when bleats, grunts and decoys were ignored and other times when one or a combination of the latter would work. I think it is controlled by the level of the bucks "desire". Pre-rut they are easy to stop, full rut is a toss-up. Keep trying though and good luck!
